Description

Lipemia centrifuging tube

Technical Field

The utility model relates to a detection device field especially relates to a lipemia centrifuging tube.

Background

Currently, as the living standard of residents is improved and the hyperlipemia population is increased and obviously younger, the lipemia specimen becomes a troublesome problem frequently encountered in daily detection in a clinical laboratory. Due to the fact that a large number of chylomicrons exist in the lipemia specimen, scattering effect can be generated on incident light, serious interference can be generated on light transmission of an optical system of a biochemical analyzer, and finally the detection result is abnormal. Although methods for eliminating the interference of the lipemia include a precipitation method, an organic solvent extraction method, a saline dilution method, a high-speed centrifugation method and the like, the former three methods all require a certain amount of solvent to be added into the original hyperlipidemic serum, the sample volume is enlarged, certain experimental errors are caused, and the added solvent interferes with the detection of some items in the sample. In contrast, high speed centrifugation is widely used in laboratories because it does not alter the original specimen composition. However, in the sample treated by the high-speed centrifugation method, because the serum to be detected is positioned at the lower layer of the chylomicron, the sample sucking head must penetrate through the chylomicron layer to suck the serum to be detected, and finally the serum to be detected becomes turbid or is mixed with the chylomicron, so that an ideal serum sample cannot be obtained. Clinical laboratories are in urgent need of a method for rapidly eliminating chylomicron in lipemia to obtain ideal serum to be detected.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a lipemia centrifuging tube can make the lipemia sample absorb smoothly after high-speed centrifugation layering and wait to examine serum.

In order to achieve the purpose, the utility model adopts the following technical proposal to realize:

the utility model discloses a lipemia centrifuge tube, which comprises a tube body and a tube cover; the tube body is made of transparent materials, and the top end of the tube body is open; the pipe cover comprises a cover body, a sealing ring and a sampling through pipe are arranged on the bottom surface of the cover body, a sampling hole is formed in the center of the cover body, the sealing ring, the sampling through pipe and the sampling hole are coaxially arranged, the sampling hole is communicated with the top end of the sampling through pipe, the sealing ring is matched with the opening, and two ends of the sampling through pipe are both sealed by tinfoil paper in a plastic package mode; when the pipe body with the tube cap is connected, sample siphunculus bottom is located the pipe body bottom.
